At the Technical University of Catalonia
(UPC), a smart room has been equipped with 85 microphones
and 8 cameras. This paper describes the setup of the
sensors, gives an overview of the underlying hardware and
software infrastructure and indicates possibilities for highand
low-level multi-modal interaction. An example of
usage of the information collected from the distributed
sensor network is explained in detail: the system supports
a group of students that have to solve a lab assignment
related problem.
